Yuck, but apparently that is the only food that a person could live on exclusively.

Unfortunately, nutritious may not equal survival, but some choices include peanut butter, dried beans, trail mix, brown rice, almond butter, frozen vegetables, sweet potatoes / yams. One person believes that you could survive on a deserted island on beans, cantaloupe, barley, kale, seaweed, fish, and berries.
Would you like to video or text chat with me?
